Find LCM of 191,985,280,278,944 with Prime Factorization
| 2 | 191, 985, 280, 278, 944 |
| 2 | 191, 985, 140, 139, 472 |
| 2 | 191, 985, 70, 139, 236 |
| 5 | 191, 985, 35, 139, 118 |
| 191, 197, 7, 139, 118 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 191 x 197 x 7 x 139 x 118 = 172804255120
Therefore, the lowest common multiple of 191,985,280,278,944 is 172804255120.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
191 x 985 x 280 x 278 x 944 = 13824340409600
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
191 : 1, 191
985 : 1, 5, 197, 985
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
278 : 1, 2, 139, 278
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,985,280,278,944, is 1.
Now, the common factors can be found like this.
191:191
985:5x 197
280:2x 2x 2x 5x 7
278:2x 139
944:2x 2x 2x 2x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 5 = 80
Therefore, the value for common factors is 80.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 13824340409600/(1x80)
LCM = 13824340409600/80
LCM = 172804255120
Thus, we can understand that the LCM of 191,985,280,278,944 is 172804255120.
